[0003]

In the above-mentioned conventional structure, there is a problem in that the accumulation portion A is formed inside the outflow pipe connecting portion (5), and the accumulation portion A easily collects dust and mud.

[0004]

[Means for Solving the Problems] As a means for solving the above-mentioned conventional problems, the present invention provides an inspection tube connecting portion (13) on the upper surface of the drainage basin (11) body (12), and at the peripheral surface thereof. Is 1 or 2
FOB tube connection (14) is provided, held out the outlet pipe connecting portion obliquely downward (15) from the bottom, the end of the flow extraction pipe connecting section (15) is an outer shell with a spherical inner surface (16A) (16) and a core tube body (17) having a spherical outer surface (17A) matching the spherical inner surface (16A) of the outer shell portion (16) and being rotatably fitted to the outer shell portion (16). ) And
The core cylinder (17) has a slope cutout (17D) at the upper end of the inner end.
And have a straight cylindrical inner surface (17B), and rotating the outer shell portion (16) DoTadashi
In the uppermost state, the inner surface (17) of the tubular core (17) is
The slope cutout (17D ) in (B) is a step on the upper side of the outflow pipe connection (15).
Continuous without any difference, within the straight cylindrical shape of the core cylinder (17) at the lower limit of rotation
The surface (17B) provides a drainage basin (11) which is continuous with the lower side of the outflow pipe connection portion (15) without a step .

[0005]

[Operation] The inspection tube connection part (13) of the main body (12) is connected with the inspection tube (19), the pipe connection part (14) is connected with a sewer pipe, etc., and the outflow pipe connection part (15) is connected. The outflow pipe (21) is connected, but the outflow pipe
The connection angle of (21) is adjusted by rotating the core cylinder (17) within the outer shell part (16) of the outflow pipe connection part (15). Then, the core tubular body (17) is formed with a sloped notch (17D) at the upper inner end.
It has a straight cylindrical inner surface (17B), and the outer shell ( 16B) is formed so that no scratches or accumulations due to steps are formed even if the core cylindrical body (17) is rotated at any angle. ) Regulates the rotation
The outflow pipe (21) connected to and connected to the core tube body (17)
Holds securely by.

[0006]

Therefore, according to the present invention, the strength of the outlet pipe connecting portion of the drainage basin is high, and
Hikkakari portion or reservoir portion has a formed between the core barrel
The cleaning tube, etc.
Kakari without also reservoir portion outflow of water from the wastewater桝内TAMARAZU dust and mud do not formed can be smoothly performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to an embodiment shown in FIGS. 1 and 2. An inspection pipe connecting portion (13) is provided on the upper surface of a main body (12) of a drainage basin (11), and a peripheral surface is provided. Receptacle part as a pipe connection part
(14) is provided, and the outflow pipe connecting portion (15) is extended obliquely downward from the bottom. The end portion of the outflow pipe connection portion (15) has an outer shell portion (16) having a spherical inner surface (16A) and a spherical outer surface (17A) matching the spherical inner surface (16A) of the outer shell portion (16). It consists of a core cylinder (17) that is rotatably fitted to the outer shell (16), and the outer shell (16) can be attached to and detached from the inner part (16B) and the inner part (16B). And an outer portion (16C) fitted to the core tubular body (17).
B), the outer portion of the straight cylindrical inner surface (17B) is expanded to form a receiving portion (17C), and the straight cylindrical inner surface (17B)
A slope cutout (17D) is formed in the upper part of the inner end . Furthermore, a packing ring (18A) is attached to the outer circumference.

In the above-mentioned structure, as shown in FIG. 1, the inspection pipe connection portion (13) is connected to the inspection pipe (19), and the receiving portion (14) is connected to the sewer pipe (20) or the like, and the outflow is caused. Core tube (1) of the tube connection (15)
Connect the outflow pipe (21) to the inlet (17C) of 7). At this time, the core cylinder (17) is restricted by the outer shell portion (16) and is rotatable from the uppermost state shown in FIG. 1 to the lowermost state shown in FIG. Can be adjusted to the top
In this state, the inner portion of the inner surface of the straight cylindrical inner surface (17B) of the core tubular body (17) is
The slope cutout (17D) is a step with the upper side of the outflow pipe connection (15).
Continuous inside, straight cylindrical inner surface of the core cylinder (17) in the lowest position
(17B) is lower and the step of Ku succession of the fluid extraction tube connecting portion (15),
Further, the outflow pipe (21) is securely held in the receiving portion (17C) of the core cylinder (17). Therefore, even in the top position, the bottom position
Even if the state, the inner surface and the core cylinder of the fluid extraction pipe connection part (15)
(17) Hikka Ri unit and the or <br/> Ri portion between the straight cylindrical inner surface (17B) of not formed.
